2 - If your transmission is from GSR whose second gear ratio is 1.90, or if it has a second gear ratio similar to 1.90, ACROSS recommends to change the second gear ratio to 2.10 (Integra Type R). To change the 1.9 to 2.1, you need Type R mainshaft and the second gear for the countershaft.
3 - If you are using our 4.928 fianl gear for your transmission, please choose A37122-16 1st gear and AR7A17-62 as the full set.
